Re: [Patch, fortran] PR35810 - [TR 15581 / F2003] Automatic reallocation on assignment to allocatable variables

[Paul Richard Thomas <paul dot richard dot thomas at gmail dot com>]

Janus,

Using -fno-realloc-lhs to compile realloc_on_assign_2.f03 is bound to
produce a segfault.  That does not trouble me.

On the other hand, the ICE with -frealloc-lhs does.  Would you be so
kind as to produce a backtrace leading up to the ICE.

Thanks

Paul
